Prescribing Habits for Androgenic Alopecia among Dermatologists in Spain in 2019-2020: A Cross-Sectional Study.

BACKGROUND: In 2017, we carried out a cross-sectional study with the aim of describing androgenic alopecia (AGA) prescription habits among dermatologists who practice in Spain. Three years later, we repeated this study with the aim of describing the current situation and comparing it with previous data. MATERIAL AND METHODS: Descriptive cross-sectional study using online questionnaires autocompleted by dermatologists working in Spain. RESULTS: The responses of 243 dermatologists were analyzed. The most common treatments prescribed for MAGA were topical minoxidil (100%), oral finasteride (92.6%), oral dutasteride (75.7%), and oral minoxidil (50.6%). For premenopausal female AGA (FAGA), the most common treatments were topical minoxidil (99%), oral contraceptives (75%), nutricosmetics (71%), and oral minoxidil (67.9%). Lastly, the most common treatments prescribed in patients with postmenopausal FAGA were topical minoxidil (99.2%), oral finasteride (79%), oral durasteride (71.6%), and oral minoxidil (63%). CONCLUSIONS: In conclusion, AGA is the most frequent alopecia in the trichology clinic. The most common treatments prescribed in male AGA (MAGA) and postmenopausal FAGA were topical minoxidil and oral finasteride, while in premenopausal FAGA, topical minoxidil, oral contraceptives, and nutricosmetics were most commonly prescribed. In the past three years, oral dutasteride and oral minoxidil have increased drastically among the most prescribed therapies for MAGA, premenopausal FAGA, and postmenopausal FAGA.
